MT5 Trade Copier: Master Account to Client Accounts
Our copy engine takes every trade from a master MT5 account and places it in each client's own MT5 account, at the client's own broker. It is written in C++, monitored trade by trade, and built for companies that run strategies for many accounts. We never hold, pool or move client money: the client's broker executes and holds the funds.
What the copy engine does
- Master to many accounts
- Opens, modifications and closes on the master are copied to every connected client account, with each account's own position sizing.
- Lot scaling and risk rules per account
- Fixed lots, balance- or equity-proportional sizing, maximum lot caps and per-account loss limits, set per client.
- Symbol mapping across brokers
- Brokers name and size instruments differently (XAUUSD, GOLD, XAUUSD.m). The engine maps symbols and contract sizes so the copied risk matches.
- Netting and hedging accounts
- MT5 netting and hedging modes treat positions differently. The engine handles both, so partial closes and reversals copy correctly.
- Monitoring and logs
- Every copied order is logged with the master price, the client fill and the delay between them, and tracked on live dashboards.
- White-label operation
- We can run the engine for you under your brand, or you license it and run it on your own infrastructure.
How a copier project runs
- 01
Requirements

Why companies use our copier
- Non-custodial by design
- Client money stays in each client's own MT5 account at their own broker. We never hold, pool, manage or withdraw it.
- Engineering, not a plug-in
- The engine is C++ built by the team that runs our own master strategy account, with the monitoring we rely on ourselves.
- Measured, not claimed
- We log the delay and price difference of every copied trade instead of quoting a headline latency number.
- A UK company
- QUANT-FX INFRASTRUCTURE LTD is registered in England and Wales and licenses technology; we do not offer signals or investment advice.
How we use it ourselves
The engine copies trades from our own master strategy account, which runs in a broker demo environment, so every change is exercised on our own flow before it reaches a client.
Companies that license the engine use the same path: the master account trades, and each end client's account mirrors it at their own regulated broker.
Licensing and pricing
The engine is licensed to companies on terms that depend on the number of accounts, the brokers involved and whether we run it for you. Bespoke copy engines are quoted at a fixed price against an agreed specification. We do not sell the copier to individual retail traders.
Frequently asked questions
- Does QuantFX hold or manage client money?
- No. Each client keeps their money in their own MT5 account at their own broker, which executes every trade. We supply the technology only.
- Can it copy between different brokers?
- Yes. The engine maps symbol names and contract sizes between brokers so the copied position carries the intended risk.
- Is this a signal or copy-trading service for individuals?
- No. We license the engine to companies, or run it for them under their brand. We do not sell signals or take on retail followers.
- What latency does the copier achieve?
- It depends on where the accounts and brokers are hosted. We measure and log the delay of every copied trade for each deployment rather than quote one number for all.
- Do we need regulatory approval to copy trades to clients?
- It depends on your jurisdiction and how you offer the service. Copying a strategy into clients' accounts can be a regulated activity in some countries, so take legal advice for your set-up. We provide technology, not regulatory permissions.
